France vested in the Alien Property Custodian Application July 14, 1942, sci-m No. 45am France July '1, 1941 3 Claims.

My invention has for its object to'provide an engined compressor-generator unit of small power and reduced size and'weight so that it may beeasily carried and lodged, more particularly on boardof an aerodyne, said unit being remarkable in that in view of this object, it comprises the combination of-a high speed interval combustion engine driving, on the one hand, on electrio generator, either directly or through the medium 'of a multiplying gear,and, on the other hand, a compressor running at a less high speed, through the medium of a reducing gear.

Another object of my invention is to provide a very flat unit that may be easilylodged in an airplane along the'side' of a wall, as for example that of the fuselage.

A further object is to provide for an efficient cooling of the engine, compressor and other hot points of the unit such as, for example, spark plug, spent gas outlet of engine, air delivery of compressor.

A still further object is to provide an engined compressorqgenerator unit intended to be used on multi-engined a'irorafts to supply the various needs. in electric current and compressed air, thereby relieving the propelling engines from this duty.

Other objects and features of the invention will appear from the following description of a preferred embodiment of the invention and be more ,fully pointed out in the claims.

cylinder engine of light weight adapted to run normally at a high speed, say of the order of 4000 revolutions per minute, for example, the cylinder I of which is carried by a rather deep vertical case 2, resting in turn on a hollow base 2; at a level somewhat higher than the latter the case 2 is provided with an overhanging extension 2a whichcarries the cylinders l of the compressor-the latter being here shown as of the two-stage type-and which serves as a provided externally with cooling fins are covcrankcase for the crank shaft I of said compressor. The crank shaft 5 is located in a common vertical plane with the crank shaft 8 of the engine and is parallel-thereto; toothed wheels 1 and 8, respectively keyed on the ends of the crank shafts 8 and 5 (the latter being at a higher level than the former) mesh together and form a reducer between the engine and the compressor. Secured on the lower portion of the crank case 2 undemeath'the overhanging P rtion 2a is the firing magneto 9, driven by a toothed wheel I0 meshing with the wheel 1 on the end of said engine crankshaft 8. The other end of the latter projects out of the crank case 2 into a chamber,

I I defined by said case and a housing I2 rising from the base 3, said chamber containing a blower or fan I3 keyed on said projecting end of the crank-shaft I. A passage Il opening at the lower part of said chamber II insures the communication between the latter and the inner space of the base 3. The part of said chamber take I9 is formed by the wall itself of the base 3, which is conveniently shaped for that purpose and constitutes at the same time the wall of the lower part of the crank case 2. 'On the end of the engine crank shaft 8 is coupled, in this instance directly, an electric generator 23 fastened onto the outside of the housing I2.

On the other hand, the cylinders I and 4 ered by elements forming a continuous cowling 25, which is preferably situated very close to the aforesaid fins and merges with the wall I2 of the aforesaid chamber II, whose inner space thus communicates with the space existing between the crank-case, the cylinders and the cowling 25.

The latter is provided with openings forming air inlets at the point 28 most removed from the fan I3 as well as at the hottest points and more particularly at point 21 round the spark plug 28 (Fig. 4), also at point 28 in order to cool the engine valves 3|, at point 2. round the engine- On the same side as this delivery pasdrivable from said engine, said compressor and I engineincluding a common crankcase provided opening E9, the inner space of the base 3 and the passage ll, thus cooling the oil cooler 20, and on the other hand, through the various air inlets of the cowling 25, through the latter and round the finned cylinders of the compressor and the engine. While this air, which is delivered by the tan l3 through the passage i6, is discharged into the open air through the opening H, in the example shown, it might as well be recovered and used, for example, for reheat ing the surrounding air or otherwise.

The invention is in nowise to be construed as limited to the details of construction as shown and described as those are only given as an example.

What I claim is:

1. An engined generator-compressor unit for use on board aerodynes including in combination a high speed internal combustion engine, an electric generator drivable from the latter, an airreciprocating compressor and a speed reducing gear through which said compressor is with an overhanging portion forming the cornpressor crankcase proper and an ignition magneto secured on said crankcase underneath said overhanging portion, the electric generator being secured on said crankcase.

'2. An engined generator-compressor unit for.

use on board aerodynes including in combination a. high speed intemai combustion engine, an electric generator drivable from the latter, an air reciprocating compressor and a speed reducing gear through which said compressor is drivable from said engine, said compressor and engine including a common crankcase provided with an overhanging portion iorming the compressor crankcase proper and an ignition magneto secured on said crankcase underneath said overhanging portion, the electric generator being se- I cured on said crankcase on the side thereof remote from said overhanging portion.

' 3. A flat engined generator compressor unit for useonboard aerodynes including in combination a high speed internal combustion engine, an electric generator located on one side of said engine and-drivable from the latter, an air compressor located-on the other side of the engine and a speed reducing gear through which said compressor is drivable from said engine, both the axes of said engine, compressor and generator being located in a common substantially vertical plane.
